[mapguide-users] Generating tiles for google maps

[George McLean]

Thanks Kori,

I tried this projection but I still get an exception error when I try 
and open the map created in MG Studio. There is a coordinate system 
field in the Map Editor form in MG Studio. Maybe I have to add this 
projection to the list of available projections? Does anyone know how to 
add projections to MG Studio?
